Speaking from personal experience, with the jobs I've personally had, if you can't tell someone else what you do for work in a single sentence, you don't have a real job

@MLE_online Single sentence: "I create instructional guides which includes writing code, writing copy, taking photos, filming videos, composing music, and doing illustrations and I also manage digital fabrication with laser cutters and 3D printers and I also manage live-streaming and do design for 2D and 3D and product development and also tech support, customer support, and occasional event support as staff for tradeshow booths."
(I work at a small company and we all do a lot.)
